S13021-01CT

One channel distance measurement photo IC for indirect TOF (time-of-flight)

1www.hamamatsu.com

The S13021-01CT is a distance measurement device using the indirect TOF method. It integrates Hamamatsu’s CMOS sen-sor and signal processing circuit. The sensor outputs signals proportional to the time for the pulse-modulated light to refl ect by the target object and return. The output value can be used to calculate the distance to the target object. The S13021-01CT runs on low voltage (3.3 V) and supports I2C interface and SPI.

When readout data is ready, DRDY is set to “assert (high).”After DRDY is set to “assert (high),” transmission is started on the microcontroller side.The microcontroller first sets CS to “assert (low),” and then sends SPCLK.When CS=low, data is output from SPDATA in sync with SPCLK when it is received.As SPDATA transitions on the rising edge of SPCLK, SPDATA is acquired on the falling edge of SPCLK.Total of 8-bit × 6=48 pieces of data can be read out.In the end, the microcontroller sets CS to “negate (high).”DRDY is set to “negate (low)” on the second rising edge of SPCLK. When data readout is ready again, it is set to “assert (high).”

Yellow indicates operations performed by the user, and blue the product’s internal operation. When the IC receives power and CLK, the built-in power-on reset circuit operates to set all registers to their initial conditions (2). To enter measurement conditions, enter com-mands via the I2C bus. To write to registers, the ADC reset bit must be asserted (reset) once (I2C command 0x00:8F) (3). After setting the conditions (4), ADC reset is deasserted (released) to start measuring (I2C command 0x00:0F) (5). In operation mode, sampling (output measurement when dark) and data saving are performed fi rst. Then, the fi rst light emission occurs. After repeating the sam-pling and data-saving operations, the data is read out. Further, the measurement count is taken, and the procedure returns to pixel re-set and repeats measurements. During this repetition, if ADC reset or ADC sleep is performed with an I2C command, the product stops its operation.
